Last week, our teacher offered us an answer to a difficulty maths problem in class. Though an answer seemed a little strange, but nobody doubted it except me. Thinking that his answer might wrong, I carefully studied the problem and tried to work them out in a different way. Half an hour late, I managed to find the correct answer. When I show my answer to him, my teacher praised me of my independent thinking.
From this experiences I have learnt that questioning can serve as a bridge that help us to find the truth.
